Difference Between Event BeginPlay and Event Tick

Overview

• Presenter: June
• Topic: Differences between Event BeginPlay and Event Tick in Unreal Engine Blueprints

Event BeginPlay

• Triggered: Once when the game starts.
• Uses: Good for events that should happen only once, like triggering a cinematic or an explosion at the start of the game.

Event Tick

• Triggered: Continuously runs as the game goes on (tied to frames per second).
• Uses: Can be used for repeating actions like animations or frequent updates.
• Performance Impact: Can significantly impact FPS if used unnecessarily; constantly feeds information.

Practical Example

• Create Blueprint Class: Actor named 'EventTick' and drag into scene.
• Blueprint Setup:
  1. Use Event BeginPlay to print a message: "Hello Event Begin"
     • Appears once when the game starts.
  2. Use Event Tick to print a message: "Hello Tick"
     • Continuously prints the message, demonstrating its constant update nature.

Best Practices

• Use Event BeginPlay: For initialization and events that only need to occur once.
• Use Event Tick sparingly: Only for necessary repetitive actions to avoid FPS impact.
